DENTAL CUSPIDOR-FIXTURE.

Specification of Letters Patent. t t 15, 1919 Application filed September 8, 1917. Serial No. 190,325.

To all whom it may concern:

Be it known that we, OSCAR H. PIEPER and ALPHONSE F. PIEPER, both of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Dental cuspidor-Fixtures; and wedo hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals thereon. l

Our present invention relates to cuspidor fixtures of the class used by dentists, which are intended to be located in proximity to a dental operating chair, and it has for its object to provide an arrangement'of parts whereby those auxiliarydevices, such as a glass for drinking water, a saliva extractor, and a finger bowl, together with the water supply nozzles for said devices, which it is desirable to locate at one side of the cus pidor, may be adjusted to any desired posi' tion about therim thereof. To this end we r .25. have provided an improved mounting for the cuspidor bowland the aforementioned parts whereby they may be shifted, or rotated, as occasion requires, andlocked securely in adjusted position. 'To theseand other ends the invention consists; in certain improvements and combinations of parts as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

p In the drawings:

Figure 1 is a perspectlve view of a fixture illustrating one embodiment of our invention in its preferred form;

Fig. 2 is a top plan view showing in full and dotted lines various positions of adjustment of the parts; Fig. 3 is a central cross-sectional view; Fig. 4 is a similar view showing a modified arrangement of the auxiliary parts and the adaptation of the drainage supporting arm as an overflow for the'cuspidor bowl.

Similar reference characters throughout the drawings indicate similar parts.

In a structure of the character to which ourpresent invention relates it is" desirable to have the bowl, which comprises the'cuspidor proper, located in a fixed position necessarily adjacent the side of the operating.

the patient toys with the operating valves and appurtenances. Thishas been found to be especially so since the fixtures comprise devices extending beyond the edge of the cuspidor such as the usual water glass holder and the saliva ejector, in conjunction with the water nozzles for each, and the usual water supply nozzle for the cuspidor itself. Our present invention, broadly stated, comprises means for mounting the so-called auxiliary devices in such a manner that they are movable in an arc concentric to the edge of the cuspidor bowl, so that when the latter 1s mounted in the most convenient position with reference to the operating chair, these parts can be adjusted wherever desired in accordance with the wishof the dentist, or operator. In illustrating the preferred form of our invention wehave shown in Figs. 1, 2 andB, the parts arranged in conjunction with the well known double, or revolving bowl, c'us pidor, comprising an outer shell 1, and an inner revolving bowl 2, which is rotated by a jet of water impinging against it from the nozzle 3. The cuspidor may be mounted on any suitable form of support, preferably in the form of a hollow arm 4:, which may also comprise a waste pipe for the water, or other fluid escaping from the bowl. The upper end of the support is disposed horizontally, as indicated by 5, and fitted therein is a collar, or coupling member, 6, having an outwardly extending flange 7, beneath which engages a coupling member, or nut 8, having the screw threaded portion shown projecting above the collar 6. Resting upon the latter, and extending upwardly therefrom is a tubular head 9 provided with screw threads at its lower end, cooperating with those of the nut 8, and having at its upper end a socket in which the shell 1 of the bowl is secured by any suitable means, such as the screw threads 10. Extending laterally and upwardly from the head 9 is a tubular arm 11, which prohends arranging, in conjunction with the parts described, the fluid, or water pipe connections, which enables them to be made of metal, whereby they move with and readily accommodate themselves to the rotaryadjustment of the parts carried on the drainage arm 11. This object we have attained by providing the main water, or fluid supply pipe with a part concentric with the axis movement of the head 9, and carrying them from a movable extension piece supplying the dischargenozzles and which is carried by the arm 11. In carrying out this feature of the invention in its preferred form the main water pipe 15 is concealed within the support 4 and extends to a lug formedinteriorly therein which is perforated and virtually comprising a portion of said pipe. Extending downwardly from the latter, and formed on the lower forward side of the support 4 is an extension, or nipple 4:, the axis of which is in alinement with the axis of rotation of the head 9. If desired a shut-off valve, indicated by 16, may be located above the extension 4 and engage with the seat formed by the end of the aperture 4. Broadly speaking the extension pipe projects from the nipple 4: to which it is attached by a pipe union 17,,in a direction laterally and upwardly to a point above the cuspidor, and is supported by the drainage arm 11. However, for convenience in construction and assembly, the pipe is made of the double bent piece 18, and the nozzle head 19, the former leading to the union 20, and the latter supported by the union 21, attached respectively to the threaded bosses on the under and upper sides of the arm 11, and between which the connecting pipe 22 extends. The head 19 carries the several valves which control the discharge of water from the various nozzles before mentioned.

It is not essential that the finger bowl discharge directly into the drainage arm, as this may be located to overflow into the cuspidor bowl, or it may be omitted and the drinking glass, or cup, holder employed alone and arranged as shown in Fig. 4, in which the overflow of the cuspidor bowl discharges into the hollow adjustable drainage arm. In this modification a single bowl type of cuspidor is shown, and indicated by 28, having the overflow aperture 24 from which a discharge pipe 25 extends outwardly and downwardly into the upper open end of the drainage arm 11, which in this instance terminates close to the periphery of the bowl23. In this type of fixture the outwardly and upwardly projecting extension of the water pipe 18 is supported on the drainage arm by means of a tubular boss 26, through which it extends. If desired said pipe may also comprise a nozzle head 27 carrying the cuspidor nozzle 28, the drinking water nozzle 29 and the valves for controlling them. The drinking cup holder 30 is also carried by the head'27 in a plane above the cuspidor bowl and is arranged with. its lip 31 overhanging the edge of the bowl. 7

Another element which usually constitutes one of the auxiliary devices is the saliva extractor, indicated by 32, which is operated by suction produced by the discharge of water from a nozzle 33, discharging into the cuspidor bowl and comprising one of the parts carried on the heads 19 and 27. When the extractor 32 is not in use it is suspended in a suitable clip 34:.

It will be seen from the illustrations that the auxiliary devices, in whatever form provided, and irrespective of the type of cuspidor with which they are used, project laterally therefrom and occupy valuable space adjacent the operating dental chair and it is, therefore, highly important that provision be made whereby they may be rotated about the axis of the cuspidor to enable the operator to dispose of them for his greatestcom venience and also to swlng them to one sldeor the other so they maynot prevent his assistant occupying the most advantageous position adjacent the side of the operating chair where the cuspidor fixture is mounted.
